The exe on our FTP seem´s to be the correct one. I DLed it yesterday evening and tested it this morning - the biggest of my distortions (which actually are something like what Bob showed) are nearly gone!

BIG thanks, Bob.
I still have some minor distortion on some points where my shieldmesh has sharp edges (exactly what Bob explained) , but I'll smooth them as soon as I get the final model of the ship.
And Tolwyn: For shieldmeshs, absolute top priority is that they are as close to the hull as possible. I think I too got some crashes before I figured that out; and those shields also only worked if shot at from a very limited amount of angles.
Second priority would then be to avoid any sharp edges, so you don't get distortions, like Bob mentioned.
( I tried to do this with my Fralthi shieldmesh, but some sharp edges still slipped into it -

)
Before this new build you also had to keep the proportions of the faces equal (like in a square) or what you can see on your pics would happen (circular ani stretched to oval shape) .
